If an intercept point (INTCPT) is computed by FMS,
"ADJUST DESIRED HDG/TRK" s-pad msg (amber) is triggered.
In the example below, DIR TO RADIAL IN 210 to BOKNO is inserted;
HDG is 350°.
− A FMS INTCPT computation is available because angle between
HDG and selected radial is less than 160°.
− INTCPT is displayed on ND but not on F-PLN page.
− FMS track is shown by a solid green line (NAV is still armed).
− Distance to INTCPT is shown as XTK error.
− INTCPT point on ND is constantly updated to reflect current track
and position with respect to the intercept radial.
When course capture criteria are satisfied:
− NAV mode is captured,
− FMA shows NAV (green).
Distance to radial for NAV
capture varies from different
criteria (e.g. Ground Speed, angle of interception).
To leave MANUAL leg in case of RADIAL OUT refer to
F-PLN sequencing in this chapter.
